As @UNBROKEN writes, it's really not a big deal about square vs rounded end tank although it's not due to the pressure, it's due to velocity. Air ends up stalling in corners effectively "rounding" the internal corner areas due to higher boundary layer friction- a 90 degree corner has greater...

I don't think it seems that slow to me- I mean, what do you want out of a 3 ton "off-road" vehicle? If someone is buying this for 0-60 times, they're buying the wrong vehicle. The Rubicon is pretty surprising in terms of performance.

It absolutely affects heat transfer negatively. To what degree depends on the thickness of the coating and whether other, more conductive powders are used in the process.

You have been told this already. He has a '20 and it will have the 4 bolt design. https://www.explorerst.org/threads/abusing-an-explorer-st-for-science.2200/post-37679

If you were to pick one, I'd suggest the SB3 Alpha. Based on pricing, warranty, polishing, etc.

Honestly, the question shows you're thinking! But, consider: when you lower temps, you lower pressure. An intercooler definitely lowers the pressure coming from the compressor by removing heat. However the increase in volume lowers velocity and increases pressure (they're inversely...

BOVs were covered substantially in another thread. Sometime in mid-year '21 Ford eliminated it from the ST. And if you're wondering what replaced it: https://www.explorerst.org/threads/2021-st-bov.2576/post-33735

The original purpose of the BOV was to eliminate boost spikes during shifts or rapid throttle transition. If you were rushing along at full boost (say 15psi), and closed the throttle, the pressure from the compressor would build up substantially with nowhere to go. This could lead to a "stall"...

Intercooler doesn't affect boost seen in the intake, it affects intake air temperature.

Never modded a DSM; had a friend with a Galant Vr-4, but I'm curious- how was boost control once you changed the exhaust? Any overboost? I had a '93 Typhoon. These were equipped with a small turbine and could reach full boost at very low rpms. So much so that there was positive boost at 70mph...

We know from several people who have posted dyno numbers it supports 500+ WHP on e50. The reality is the stock exhaust will support the limits of the stock turbos. FIgure approx 600 crank HP. Above that, you need to upgrade turbos, downpipes, etc. I don't know of anyone who has updated the...

Agree. But they didn't. And they won't. For whatever reason: engineers miscalculated, a bad batch of bolts, sold more STs than expected, had to improvise during the pandemic, etc. All of these things have been debated ad infinitum on this forum. The fact remains- if you're worried about it...

I would not hesitate to install the AWR brace. It's much easier and cheaper than the subframe. (Although I'd still like to see it extended to include another differential cover bolt) Given Ford's communication and fixes to the bolt, I really don't foresee any invalidations of warranty claims by...

Just FYI, in my opinion- don't bother with the downpipes until you decide to change out the turbos. At this point, they won't make any real difference (10hp?) and you'll save a lot of money on the install by doing both at the same time. Have you ordered the Timberline rear diff yet?

Problems like the OP is facing are very difficult to resolve. At one time, shifting into reverse triggered an actual physical switch that led to the backup lights. Pretty easy to trace a wiring problem or a switch problem. Now, you shift into reverse which just puts info on the CANBUS saying...

I'm sorry you didn't like my categorization. But, you received the tune on Monday and installed it after work, according to you. Three days later (Thursday pm) you claimed "several more MPGs". Besides "shill", is there another adjective you'd like me to use?

I shouldn't have stated "increasing timing does NOT increase emissions." I was thinking about THC emissions representing unburnt fuel which would affect mileage. But you're right, the timing does play a role in the type of emissions (COx or NOx or HC) as well as a ton of other factors. The...

I'm sorry to have to correct you on this point, but increasing timing does NOT increase emissions- it decreases them by not only achieving better fuel burn, but my generating more power resulting in needing less fuel. A win-win.. Anecdotal observations of people who've had the tune for a "few...

You can remote start directly from the fob.

I understand my cajun friend. Lake Charles is a cool place. Been through there a few times. My french is good, but not great . I agree, let the good times roll!
